Abstract

Procedure and plant for wet-dry purification of smoke by separation of SO<sub>2</sub>. A suspension of finely-ground limestone is added to a reactor (1) via an oxidation and acidification unit (9), where the finely-ground limestone is mixed with returned dust (3) and air, oxygen and/or some of the smoke (10). Preferably, the returned dust is also subjected to reactivation by wet-grounding (8).
